What is the only way to completely prevent current flow through a lineworker's body while contacting an energized line?

Current can only flow if there is a complete conductive path from the energized line through the worker to something else. The surest way to stop that path is to create a non-conductive barrier between the worker and the live parts and to physically keep the worker insulated from them. When you properly insulate and isolate, you prevent any potential circuit connection to ground or to other conductors, so even though the line may be energized, there is no path for current to travel through the body. Protective gloves or dielectric boots, while helpful, do not guarantee zero current because insulation can be damaged, moisture can compromise effectiveness, and there are scenarios (like backfeeds or stored energy) where a path could still exist. De-energizing a circuit is essential and greatly reduces risk, but the guarantee of zero current when contacting a live line comes from creating a solid insulating barrier and ensuring the line is isolated from the worker’s reach.
